PORT LIGHT.

Application filed December 20, 1922. Serial No. 608,038.

To all whom it may concern Be it known that 1, JOHN H. ALEXANDER, citizen of the Dominion of Canada, residing at Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Port Lights, of which the following is a specification.

This invention relates toa swiveling port light for vessels, which is designed to supplement the existing hinged port light and afford facility for better ventilation therethrough.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. 1 is a. vertical section through the port light aperture showing the hinged port light as open.

Fig. 2 is a face View of the same from the inside. a

Fig. 3 is a plan showing the hinge connection at the supplementary light.

Fig. 1 is a face view of the supplementary glass.

Fig. 5 is an edge view of the pivotal stem.

Fig. 6 is an enlarged detail being a section of the upper pivot connection of the stem.

Fig. 7 shows a modified form of the invent-ion as applied when the hinged port light moves about a horizontal axis.

Fig. 8 is a plan of the same.

Fig. 9 is an enlarged sectional detail on the line 99 in Fig. 7.

In these drawings 2 represents the frame of the existing port light, the framed glass 3 of which is hinged at l to open inward, and when closed is tightened against the frame 2 by a screw and nut 5. Though this port light may be opened to admit air in line weather, it does not effectively ventilate the cabin, as there is no provision for directing the current of air, due to the movement of the vessel, into the space within. It is to provide such and enable the current to be directed as desired into the room, or to induce an outward flow of air, that the supplementary swivel glass, which is the particular subiect of this a plication, is applied.

It comprises a disc 6 of glass, or other suitable material, corresponding in diameter approximately to the inner circle of the frame 2, which disc is secured in the slot 7 of an axial supporting stem 8 by a screw pin 9 inserted through the upper and lower end of the supporting stem 8 and engaging small notches 1O ground in the diametrically opp0s1te edges of the glass 6.

This glass disc 6 in its stem 8 is required to be supported concentrically within the" frame 2 in a manner that will permit it to the upper end of 8 an axial chamber 11, the

outer end of which is threaded to receive a bushing 12 within which bushing is a headed pin 13. The outer end of this pin is threaded, as at 14, to be screwed into an aperture provided for it in a hinge member .15 which is apertured at 16 to receive a hinge pin or bolt 17, which is fitted through a small hinge bracket 18 secured to the upper part of the frame 2. I

The aperture which receives the screw 14: of the swivel pin 13 is produced as at 19 on the other side of the hinge aperture 16, ,to enable a screw driver to be inserted to retate the pin 13 to connect it tothe hinge member 15, and the bushing 12 is also provided with notches to enable it to be rotated in connecting the swivel pin 13 within the chambering 11.

The supplementary light 6 is thus suspended on the head of the pin l3 on which it may be turned as a swivehor it may be lifted clear of the port aperture'o-n the hinge pin 17 to the position indicated by dot and dash lines in Fig. 1.

The lower end of the supporting stem 8 is reduced as at 20 to fit a half bearing between the open jaws of a keeper 21 in which it is retained by a pin 22.

lVhen not required for use, the swiveling light 6 is lifted upward to the position shown by dot and dash lines in Fig. 1, and connected to the underside of the deck within the cab-in by a light chain 23 having a link or other attachment which may be connected to the free end 20 of the swivel, light stem, in which position the normal port light 3 may be closed and secured to its frame by the nut 5.

Where the port light 3 is hinged to the upper side of the frame 2, as is sometimes the case, as it is desirable that the draught directing supplementary disc 6 should swivel about a vertical axis, its stem 8 is axially mounted in the free ends of a hemispherical frame which is jawed at 26 to'receive the pin 27 of a hinge member 28 secured to the frame 2 clear of the ring frame of the port light 3 when the same is seated or closed on the frame.

By this manner of mounting, the supplementary frame 25 of the supplementary light may be swung clear of the port light 3 to enable the same to close, and when the port light is opened, the frame 25 may be moved to bring the axis of the supplementary light 6 diametrically across the port opening, that it may be swiveled to direct the air Within the cabin.

Members 29 may project from the face of .the frame 2 to engage and support the hemispherical frame 25 concentric with the port opening when the disc 6 is in use. On the outer faces of these projections 29 clips 30 may be pivotally mounted to turn across the edge of the frame 25 and retain it in position against any tendency to swing away from the. port opening when the boat rolls.

Although the disc 6 is described and illustrated as made of glass, which is preferable, it may obviously be made of thin sheet metal in which case the trunnion ends may be attached in any convenient manner to the body of the disc without the requirement of the stem being slotted as to receive the glass.

The invention forms a desirable attachment or supplementary addition to a port light, enabling a current of fresh air to be circulated through the cabin when the port light is open, as one half of the supplementary disc or glass projects from the ships side and engages and directs the air into the cabin. When not in use, it forms no impediment to closure of the normal portlight.

It is not only an inexpensive addition, but can be readily applied to existing port lights.

Having now particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. In a port light, the combination with the frame of the port to which the port light is hinge-connected, a supplementary disc, swivel-mounted to turn about a vertical axis parallel to the plane of the frame, and means permitting movement of the supplementary plate clear of the port to permit closure of the normal port light.

2. In a port light, the combination with the frame of the port to which frame the closing glass is hinge-connected, of a supplementary plate of glass dimensioned slightly less than the port, means for mounting said supplementary platein bearings connected to the port frame to turn on a vertical axis parallel to the plane of the frame, one of said supporting bearings being hinge-connected to the frame to enable the supplementary plate to be moved clear of the port and permit closure of the normal port light.

8. In a port light, the combination with the frame of the port to which frame the port light is hinge-connected, a supplementary disc slightly smaller than the port, diametrically opposite pivots secured to the discs, bearings connected to the frame of the port in which bearings the pivots of the disc are mounted, and means for hinge-connecting one pivot bearing to the frame that the disc may be moved clear of the port opening and permit closure of the normal port light.

4. In a port light, the combination with the frame of the port to which frame the glass of the port light is hinge-connected, a supplementary disc slightly smaller than the port, a vertically disposed stem to which the supplementary disc is secured, an open bearing secured to the frame adapted to receive the lower end of the stem, removable means for retaining that lower end in its bearing, a pivotal bearing for the upper end of the stem, means for hinge-connecting the pivotal bearing of the upper end to thle port frame to turn on an axis normal that of the stem whereby on the lower bearing being released, the supplementary disc and its carrying stem may be turned clear of the port opening to permit closure of the normal port light.

5. In a port light, the combination with the frame of the port to which frame the glass of the port light is hinge-connected, a member secured to the upper side of the port frame, said member supporting a hinge pin, the axis of which is horizontally disposed parallel to the face of the frame, a hinge member mounted on the pin, a stem pivotally movable in the hinge member and connected. thereto, an open bearing secured to the lower part of the port frame and adapted to receive the lower end of the stem, removable means for retaining the end of the stem in the open bearing, and a disc ecured to the stem to be concentric with .he port.

JOHN HYSLOP ALEXANDER.
